C = 11n; continuous
C = 11 n ; continuous
C = 11 + n; discrete
C = 11 + n ; discrete
C = 11 + n; continuous
C = 11 + n ; continuous
C = 11n; discrete
C = 11n; discrete
The formula for the cost C of n DVDs is C = 11n. This means that the cost of the DVDs is calculated by multiplying the quantity of DVDs, n, by the price per DVD, which is $11.
Now, let's determine whether the situation is discrete or continuous. In this case, the quantity n represents a whole number, as you can only buy a whole number of DVDs. Therefore, the situation is discrete, since it deals with a countable number of items.
So, the correct answer is: C = 11n; discrete.
